label_log: Label numbers in log format (10^3, 10^6, etc)
Description
label_log() displays numbers as base^exponent, using superscript formatting.
Usage
label_log(base = 10, digits = 3)
Value
All label_() functions return a "labelling" function, i.e. a function that
takes a vector x and returns a character vector of length(x) giving a
label for each input value.
Labelling functions are designed to be used with the labels argument of
ggplot2 scales. The examples demonstrate their use with x scales, but
they work similarly for all scales, including those that generate legends
rather than axes.
Arguments
base
Base of logarithm to use
digits
Number of significant digits to show for the exponent. Argument
is passed on to base::format().
